Physics - Gravitation Question with Solution | TestHub

A spaceship orbits around a planet at a height of$20\mathrm{ }\mathrm{k}\mathrm{m}$from its surface. Assuming that only gravitational field of the planet acts on the spaceship, what will be the number of complete revolutions made by the spaceship in$24$hours around the planet?
[Given: Mass of planet$=8\times {10}^{22}\mathrm{ }\mathrm{k}\mathrm{g}$,
Radius of planet$=2\times {10}^6\mathrm{ }\mathrm{m},$
Gravitational constant$\mathrm{G}=6.67\times {10}^{-11}\mathrm{ }\mathrm{N}{\mathrm{m}}^2/\mathrm{k}{\mathrm{g}}^2$]
